Apple has added features to its iWork.com public beta. It’s a service Apple is developing to share iWork ’09 documents online.

Using your Apple ID, just click the iWork.com icon in the Keynote, Pages or Numbers toolbar to upload your document and invite others to view it online. Viewers can provide comments and notes, and download a copy of your document in iWork, Microsoft Office or PDF formats. A consolidated online list of all your shared documents indicates when your viewers have posted comments.

With the latest public beta, you can share links to yourdocuments via social networking services. What’s more, there’s an updated interface for iPhone and iPod touch users to access info.

iWork ’09 is available through the Apple Store (http://www.apple.com), Apple’s retail stores and Apple Authorized Resellers for a suggested retail price of US$79. iWork ’09 is available for $49 with the purchase of any Mac through the Apple Store, Apple’s retail stores and Apple Authorized Resellers.
